Be-it lrnown that I; CI-rARLns- A. PILQrIIsT a citiienoi tlroUnited-States, residingiat N'css City, in the county of Nessand State I of Kansas, have invented certain 'new* and 1 useful Improvementsin- Oil-Burners, of"

which the following-is a specification;

This 'inventio n= relates tooil burners, and is SOHlGWhflFSlfiTllL'I' toa-th'eburner dlSClOSGCl in any U S; Letters Patent No. 1,232,392,

datedJuly 3', 1917; the"chief difi erence being" that the present burner is more espe cially adapted to the consumption-0 f crudeoil although the lighter hydroca rbonoils,

such as kerosene,distillate, etc,- can-alsobe used economically;

In carrying out the invention, it will be understood that the essential featuresthereof maybe changed witl'iin-tl e'spirit and scope of the claims, and an order that the invention may be fully understood, reference will'i ow be made to the accompanying" drawing, in which:

Figure 1 is a central, vertical, sectional view of a burner in the fire box of a stove.

Fig. 2 is an inverted, plan view of a flame spreader forming a part of the invention.

Fig. 3 is a plan view of an oil spreader.

Fig. 4 is an inverted plan view of the oil spreader.

A designates the fire box of a stove, B the grate thereof, C a sheet metal plate covering the grate B, and D asbestos cement laid to the desired thickness upon the plate 0 to prevent the passage of air through the grate, except at its central portion where an air supply pipe 1, extends upwardly a suitable height.

3 designates an annular trough-shaped generator encircling the air pipe 1 and having its bottom portion slightly embedded in the asbestos cement D. r

5 designates an oil spreader consisting of a circular plate which is crowned as disclosed by Fig, 1, to distribute the oil uniformly over the upper surface thereof as it flows from a supply pipe 7. The oil spreader 5 is provided at its underside with legs 9, having shoulders to rest upon the inner annular margin of the generator 3. The legs 9 are provided with depending guides 11, which enter the centralopening in the generator 3 and also secure the oil spreader 5 from lateral displacement when in position upon said generator? l ugs ltt project upwardly from the top ofthe oil sp read'er 5 I to support 'a hflame spreader 16*, spaced slightly above said oil spreader to avoid ob' structinig the flOwoifibil fr'oin th e"discharge end"- ofth e pipe 7 The-flame spreader le consists *of a: circular plate having a verti call yl depending margmarflange 18 loosely= embracing the vertically depending iiiarginal flange"- 5 'of the oil{ spread'er* 5", which latter has peripheral I spacingmembers' T 20 that} serve to center the flanie spreader thereon;

Iir practice the bottom of the 3 generator 3' is provided' with a wi'clr 24ai1d tlie oil pipe-lscone-ease to a suitab-le*-source=*(not shown) and provided with valve (not shown) for controlling the-flow of "oil tli'ere througln As the oil discharges fr'om the pipe-*7 ,-it overflows the "oil spreader 5 in -all directionsand runs down into the generator 3'," whereit saturat'estliewick' 245 The satu'- rated "wick is then ignited and as the resultant flame ascends to escape through the annular opening between the upper margin of the generator 8and the lower edge of the flange 18, it impinges against said flange 1S and the margin of the oil spreader 5, thus heating the same to a sufficient degree to convert the oil into gas before reaching the margin of said oil spreader 5. As the gas thus generated in the chamber 32 between the oil spreader 5 and the flame spreader 16, passes downward through the spaces between the margin of said oil spreader 5 and the flange 18, it becomes thoroughly mixed with the air supplied through the pipe 1, thus forming a highly combustible mixture, the flame from which is spread by the flame spreader 16 and passes from the opening 30 in a continuous annular sheet which impinges against the walls of the fire box A, and thus quickly heats the same to a. high degree' The air be comes heated as it ascends through the pipe 1 and comes into contact with the oil spreader 5 and thus readily commingles with the highly heated gas discharged from the chamber between spreaders 5 and 16. As the oil supply pipe 1 is not exposed to the flame, it does not become choked with soot or carbon. Should carbon form on the spreaders 5 and 16, they can be readily cleaned on removing them through the stove door. Should any part of the burner become defective, it can be readily replaced by ano her part Without discarding other members of the burner.-

By only slightly crowning the top of the oil spreader 5, the flow of the oil is retarded sufliciently to permit it to become thoroughly vaporized in the gas chamber 32'a'fter the spreaders 5 and 16 areheated, and hence there is no danger of unvaporized oil flowing into the generator 3. c

Having thus described my invention, what I claim and desire to secure by Letters Patent, is:

1. In combination With a fire box, a sheet metal plate laid upon the grate in said fire box and having a central opening therein, an air supply tube extending upwardly from the central opening in said plate, an annular trough-shaped generator arranged above the plate, aWick in the bottom of said generator, an oil distributer superimposed on said generator and provided with a crowned upper surface, an oil supply pipe communicating with the upper surface of the oil distributer, a flame spreader having a depending marginal flange loosely embracing the margin of the oil distributer and spaced from the top of the generator to leave an opening, for the purpose described, and fire proof material covering the sheet metal plate and surrounding the air supply tube and the generator, for the purpose specified.

2. An oil burner comprising a centrally disposed air tube, an annular trough-shaped generator of V-shaped cross section separable from but embracing said air tube, an oil spreader plate having depending legs engaging the upper inner margin of said generator, the top of said plate being slightly crowned, a vertically depending marginal flange on the oil spreader plate having peripheral spacing lugs, a flame spreader plate superimposed on the oil spreader plate but spaced therefrom to leave an intervening gas chamber, a vertically depending marginal flange on said flame spreader plate loosely embracing the spacing lugs on the flange of the oil spreader plate, and an oil supply pipe extending upwardly through the central portion of the oil distributer plate, substan- Li;

tially as described.

In testlmony whereof I aflix my signature, in the presence of two witnesses.
